We live in West End NC and the soil is sandy and many pines in the area. Our yard is shady and sunny throughout the day. What type of grass would grow best in these conditions? It is now centipede, but it is dying out over time, and as the yard gets more shady (trees get bigger).
Centipede grass is only considered a fair grass for shade. Better ones to try include a combination of Kentucky bluegrass and fine fescue or a combination of Kentucky bluegrass, tall fescue and fine fescue. This article tells more:

In parts there was about 10cm of new soil laid and turf on top. In places the turf is nice and green but its like there is a massive air bubble underneath so its all moving when you walk on it...??
These grass bubbles tend to be caused by trapped water on rocky or poor soils. This can happen with fertile soils in waterlogged areas as well.To address grass bubbles in your lawn, start by aerating the soil to improve drainage and reduce compaction. Consider dethatching to remove excess organic matter and mow at the correct height to prevent stress on the grass. Proper irrigation practices, including deep watering and watering early in the morning, can help prevent excess moisture buildup. Additionally, fertilize appropriately and address any low-lying areas where water tends to accumulate. If the problem persists, then you may need the assistance of your closest local extension service.
